I would suggest looking at ratemyprofessor and looking for a professor that is relatively easy. Once I took a speech class thinking it would be an "Easy A" but it turned out to be one of the hardest classes because my teacher gave a lot of assignments & had high expectations. So I would go by the professor & not so much by the subject.
it depends on what sort of linguistics it is, what your major is, what your strengths are in general....
...linguistics at the structural levels can get pretty intense for people who are used to english lit, but if you're coming at it from the science end it's way easier than that.
...at the historic and social levels then yeah it's a piece of cake if you're ok with essays and stuff.
Hope it goes well.
it's very much about having a rigorously systematic approach, like solving equations in a way... or logic gate flow charts.
if you're ok with it, it's like sudoku. if you're not, it's a nightmare.
it's worth it though if you're interested in how language works...
If you want a course that's interesting, informative, relatively easy to get a good grade and will aid your well roundedness, take anything in the Humanities.
